Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. We employ advanced analytical techniques including HPLC, NMR, and IR spectroscopy for precise identification and purity verification. Certificates of Analysis (COA) detailing all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
